In the field of industrial automation, frequency inverters serve as the core equipment for motor control, with their performance directly impacting the efficiency and stability of production lines. As a global leading supplier of drive and automation technology, Germany-based LENZE has made its 8200 Vector series frequency inverters the preferred choice for numerous industrial clients, thanks to their modular design, high-precision control, and broad application adaptability.

I. Product Overview: Modular Design, Flexible Adaptation
The LENZE E82EV402K4C belongs to the 8200 Vector series of vector frequency inverters, offering a power range from 0.25kW to 90kW to meet diverse needs from light to heavy loads. The specific parameters of this model are as follows:

• · Power: 4.0kW (400V three-phase power supply)
• · Current: 7.3A
• · Cooling Method: Supports "external heat sink" or "cold plate technology," adapting to different installation environments
• · Operating Interface: Optional XT operating module or free debugging via the PC-based GlobalDrive Control easy software

One of its core advantages is its modular design: users can easily integrate the frequency inverter into equipment or factory automation systems through pluggable functional modules, while saving control cabinet space. Additionally, models above 3kW are equipped with a built-in "safe stop" function, complying with industrial safety standards.

II. Technical Highlights: Precise Control, High Efficiency, and Energy Saving
1. Vector Control Technology
The E82EV402K4C adopts advanced vector control algorithms to achieve the following performances:

· Speed Control: Wide setting range (1:50), with a steady-state speed accuracy of 0.5%, ensuring linear deviation of less than 0.1Hz without external feedback.

· Torque Control: Overload capacity up to 180% (instantaneous), with a torque rise time of only 200ms, ensuring rapid and stable dynamic response.

2. Application Scenarios
Based on its control capabilities, this frequency inverter is widely applied in:

• · Material Handling: Achieving smooth start-stop through S-curve generators to reduce mechanical shock.
• · Pump and Fan Drives: Supporting quick restart functions to optimize energy consumption.
• · Process Control: Built-in PID controller, suitable for closed-loop control scenarios such as pressure, flow, and tension regulation.

3. Energy Efficiency and Reliability

· Efficient Cooling System: Two cooling technologies are available, adapting to high-temperature or enclosed environments.

· Maintenance Convenience: Modular design supports rapid replacement of heat sinks and electronic components, shortening downtime.

III. Industrial Applications: Comprehensive Empowerment from Logistics to Manufacturing
1. Intralogistics
In automated warehousing or conveyor systems, the E82EV402K4C can drive conveyor belts, sorting equipment, etc., improving material flow efficiency through precise speed synchronization and positioning control. For example, in e-commerce warehouses, its rapid response capability reduces package sorting errors.

2. Manufacturing and Processing

• · Machine Tool Industry: As a spindle drive, it achieves low-speed high-torque output, ensuring machining accuracy.
• · Textile Machinery: Controls winding tension to avoid wire breakage or fabric deformation.

3. Energy Sector
When driving water pumps or fans, variable frequency speed regulation enables on-demand flow supply, achieving energy savings of over 30% compared to traditional fixed-frequency operation.

IV. User Value: Real-world Cases of Cost Reduction and Efficiency Enhancement
Case 1: An Auto Parts Factory

• · Problem: Frequent start-stop of production line conveyor belts led to motor overheating and high maintenance costs.
• · Solution: After replacing with the E82EV402K4C, mechanical shock was reduced through S-curve control, resulting in a 60% decrease in failure rate and an annual maintenance cost reduction of approximately 150,000 yuan.

Case 2: A Sewage Treatment Plant

· Problem: Pumps operated under fixed frequency for a long time, causing significant energy waste.

· Solution: After adopting variable frequency drive, speed was automatically adjusted based on liquid levels, achieving an annual energy saving of 80,000 kWh and an investment payback period of only 18 months.
